Safety Instructions
Use the following safety guidelines to ensure your own personal safety and to
protect your equipment and working environment from potential damage.
For complete safety and regulatory information, see the safety instructions
that shipped with your equipment. Warranty information may be included in
this document or as a separate document.
SAFETY: Rack Mounting of Systems
Observe the following precautions for rack stability and safety. Also see the
rack installation documentation accompanying the system and the rack for
specific caution statements and procedures.
Systems are considered to be components in a rack. Component refers to any
system as well as to various peripherals or supporting hardware.
CAUTION: Instructions for Rack-Mounted Systems:
• Your rack kit has been approved only for the rack cabinet provided.
It is your responsibility to ensure that installation of the equipment
into any other rack complies with all applicable standards. Dell disclaims
all liability and warranties with respect to combinations of equipment
with any other rack.
• The rack enclosure is cooled by air through the vented tiles of a raised
floor. The rack enclosure should be positioned over the vented tiles before
installing components in the enclosure.
• Before installing your equipment in a rack, ensure that the rack is properly
secured as directed in "Installing the Rack Stabilizer Feet" on page 31.
• Always load from the bottom up and load the heaviest items first.
• Do not overload the AC power supply branch circuit that provides
power to the rack.
• Do not stand or step on any components in the rack.

6Installation Guide
• The air channel located at the bottom of the rack is used to direct cool air
from the floor to the front of the rack enclosure. The air channel must
always remain at the bottom of the rack (in 1U and 2U) and must not be
moved to a different location in the rack.
• Do not use the air channel as a step or as a shelf to support components.
WARNING: All brushes supplied must be installed and the brush bristles must be
in contact with the floor to form a seal around the bottom perimeter of the rack
enclosure. Removing the brushes may reduce the cooling efficiency within the
enclosure.
WARNING: The extension service cover must only be removed when installing or
removing components from the upper rack unit spaces and must be reinstalled
immediately. Components in the rack may overheat if the extension service cover
is not installed in the rack enclosure.
Rack Installation Instructions
This installation guide provides instructions for trained service technicians
installing a rack enclosure. Information includes assembling the rack,
coupling two racks, and routing cables through the rack. The rack can be
installed using the recommended tools.
Before attempting this installation, read through this entire procedure carefully.
Rack Specifications
NOTE: The rack meets the specifications of American National Standards Institute
(ANSI), Electronics Components Association (ECA) Standard EIA/ECA-310-E,
International Electrotechnical Commission (IEC) 60297-3-100, and Deutsche Industrie
Norm (DIN) 41494.

Installation Guide 7
Before You Begin
WARNING: Before you begin installing your rack, carefully read "Important
Safety Information" on page 7 and the safety instructions that came with the rack.
WARNING: When installing multiple systems in a rack, complete all the
procedures for the current system before attempting to install the next system.
WARNING: Rack cabinets can be extremely heavy and can move easily on the
casters. The cabinet has no brakes. Use extreme caution while moving the rack
cabinet. Retract the leveling feet when relocating the rack cabinet. Avoid long or
steep inclines, rough surfaces, or ramps where loss of cabinet control may occur.
Extend the leveling feet for support and to prevent the cabinet from rolling.
WARNING: Avoid rolling the rack cabinet over rough surfaces. Hard impacts to
the casters could cause them to break and the rack can become unstable and may
tip over.
WARNING: Do not attempt to move your rack with components installed.If you
move a fully loaded rack on a slightly uneven surface, the rack can become
unstable and may tip over.
Important Safety Information
Observe the safety precautions in the following subsections when installing
your system in the rack.
WARNING: You must strictly follow the procedures in this document to protect
yourself as well as others who may be involved. Your system may be very large
and heavy and proper preparation and planning are important to prevent injury
to yourself and to others. This becomes increasingly important when systems
are installed high up in the rack. Also verify that the vented tiles and floor sub-
structure are rated to support the weight of the rack enclosure with all the
components installed.
WARNING: Before installing systems in a rack, install front and side stabilizers
on stand-alone racks or the front stabilizers on racks joined to other racks.
Failure to install stabilizers accordingly before installing systems in a rack
could cause the rack to tip over, potentially resulting in bodily injury under certain
circumstances.
WARNING: After installing systems in a rack, never pull more than one system
out of the rack on its slide assemblies at one time. The weight of more than one
extended system could cause the rack to tip over and cause injury.
